arrays......

allworknoplay · 04-10-2009, 11:50 AM

Is there an easy way to print the items of an array without using print_r or var_dump and without using any loops?
I don't want to show key to value relationship like var_dump and print_r shows.... just the items in the array. And no loops...

For example:

$array = array(1,2,3,4,5);

Let's say there's a function called: print_array

Then I would do this:

print_array($array);

And it would spit out: 1 2 3 4 5

I checked out PHP.net but didn't see anything under the print_r function...maybe one of you guys know of some other function?

I just realized I can just make my own function to do this, so I think I will do just that.

But if anyone knows of any quick function call that can do this let me know because if PHP has it already built in, there's no need to reinvent the wheel....

There might be a premade function for it, but a simple for each loop would do the trick. Its hardly a wheel to reinvent.

right, I know, I want to avoid any loops, I'm working on a pagination script and I have an idea about how to do something but I didn't want to use loops because I wanted to keep it clean and straightforward.

In any event, I'll have to just make my own function that should be able to spit it right out the way I wanted...

PHP Code:


			
function print_array($array)
{

     foreach($array as $element)
     {

          echo $element . ' ';

     }

}

$array = array(1, 2, 3, 4, 5, 6);
print_array($array); //output: 1 2 3 4 5 6

print_r($array);

or

<pre><?php print_r($array); ?></pre>

Edit: Sorry didn't read your post properly!

although i don't see why a simple foreach would be a problem, you could do something like this:

PHP Code:


			
array_walk($array, create_function('$val', 'echo $val, \'<br />\';'));

$array = array(1, 2, 3, 4, 5, 6);

print_array($array); //output: 1 2 3 4 5 6

lol, that is exactly what I was looking to do, hoping PHP had a simple built in function but guess not. I will need to incorporate this into my paginate function, then you'll see what I was trying to do...

No, print_r and var_dump provides a very un-elegant printout.

Look at tanax's example, that is what I was looking for but wanted to make sure that PHP didn't have something like this already built in..

I know, wait till I finish my pagination code and you guys will see why I was looking for a one function, quick straight simple printout...

It's not just simply using a small simple loop to print it out, it's the way in which I would like to use it...

PHP Code:


			
echo implode(' ', $array);

Though making a custom function with a foreach loop provides more functionality for future extensions, this will work quite alright with what he wanted.

Why would you want to extend echoing an array's values, with more functionality?!

I don't know.
For instance, he might want to run an if-statement to check something on each element. Add something around each element. Well.. you get the point. But since he just wanted to echo out the array(at least right now) - imploding the array will work great.

Here's the link to my thread where I use the implode function. It will explain why I was looking to "echo" out the items in the array in one clean shot...

Pagination Function

allworknoplay · 04-17-2009, 02:07 PM

Hey guys, I believe I got this part working. It's for my pagination script. The purpose is to show the first 2 and last 2 links with the current page in the middle like so:

current page is: 7

5 6 7 8 9

current page is: 2

1 2 3 4

current page is: 10

8 9 10 11 12

So what I do is use a FOR loop and only take what's in the conditions and put into an array.
Here's the code...

Code:

/* CURRENT PAGE */
$get_page = 13;

/* SIMULATE AVAILABLE PAGES BY USING ARRAY FOR TESTING */
$array = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14);

$count = count($array);

/* WE WANT THE FIRST 2 AND LAST 2 LINKS */
for($i=0;$i<=$count;$i++) {

	if((($get_page - 2) == $array[$i]) || (($get_page - 1) == $array[$i]) || ($get_page == $array[$i]) || (($get_page + 1) == $array[$i]) || (($get_page + 2) == $array[$i])) {
	
	$array2[] = $array[$i];
	}



}

This returns:

11 12 13 14

Since 14 is the last page, there is no page 15....

Comments/criticisms?

allworknoplay · 04-17-2009, 02:13 PM

I made my FOR LOOP a little cleaner...it works this way too...
I am open to suggestions to make it even better...

Maybe using SWITCH might be a little faster?

Code:

for($i=0;$i<=$count;$i++) {

	
if(($get_page - 2) == $array[$i]) $array2[] = $array[$i];
if(($get_page - 1) == $array[$i]) $array2[] = $array[$i];
if($get_page == $array[$i]) $array2[] = $array[$i];
if(($get_page + 1) == $array[$i]) $array2[] = $array[$i];
if(($get_page + 2) == $array[$i]) $array2[] = $array[$i];
	
}
